libata: update libata core layer to use devres
Update libata core layer to use devres.
* ata_device_add() acquires all resources in managed mode.
* ata_host is allocated as devres associated with ata_host_release.
* Port attached status is handled as devres associated with
ata_host_attach_release().
* Initialization failure and host removal is handedl by releasing
devres group.
* Except for ata_scsi_release() removal, LLD interface remains the
same. Some functions use hacky is_managed test to support both
managed and unmanaged devices. These will go away once all LLDs are
updated to use devres.
